When you moved past the econo-potato styling of the last generation Sentra and got behind the wheel of the SE-R variant, you'd experience an entertaining FWD ride. Especially when modded out in S- or R-tune, the SE-R Spec V was a capable backroad carver and a suitable daily driver.

As expected, Nissan has announced that their newest hot-rod Sentra is on its way and will make its debut later this month at the Los Angeles Auto Show.

Available in both SE-R and SE-R Spec V trim, the latter getting a high-output version of Nissan's 2.5-liter inline four, with power likely being directed via a six-speed manual gearbox. We'd expect power output of the new vehicle to be somewhere in the 180 to 185 HP range, with torque coming in around 190 ft.-lbs. For those of you disenfranchised by the torque output of similar naturally aspirated offerings (I'm talking to you Civic Si), rest assured that Nissan always brings the twist.

The full press release is available after the jump.

PRESS RELEASE

2007 Nissan Sentra SE-R to Debut at L.A. Auto Show [Nov. 3, 06]

NASHVILLE (Nov. 3. 2006) – Nissan North America, Inc. (NNA) today announced that it will introduce two exciting new performance vehicles at the Los Angeles Auto Show, November 29th, at the Los Angeles Convention Center.

All-new for 2007, the Nissan Sentra will once again have SE-R high performance models; both SE-R and SE-R Spec V. As a pioneer model in the field of sport compact cars, the 2007 Nissan Sentra SE-R offers more power, performance and technology to this highly acclaimed model. The SE-R Spec V model will be powered by a specifically designed high-output version of Nissan's 2.5-liter DOHC 4-cylinder engine. Additional information on the SE-R with be announced at the LA Auto Show on November 29th.

Nissan will also showcase another uniquely styled, exhilarating performance-oriented vehicle, which marks Nissan's entry into a previously untapped customer segment. Details on the second world debut vehicle are being withheld until Nissan's press conference on November 29 at 10:00AM PST.

In addition, Nissan will participate in the 2006 Hybrids and Green Cars/LA event that takes place during the media days portion of the Los Angeles Auto Show on Wednesday, November 29 and Thursday, November 30. This event will allow attendees an opportunity to drive many advanced technology vehicles from various manufacturers.

Nissan will showcase three products at this ride and drive, including the 2007 Altima Hybrid, the X-Trail Fuel Cell Vehicle and the 2007 Armada Flexible Fuel Vehicle (FFV).

      torque is a function of every component and charastic of an engine. hp is a function of torque and rpm.
      • 8 Years Ago
      Wow, I can't believe the blatantly arbitrary perceptions some of you guys have about engine technology. Horsepower is a function of torque, and yes, increasing the rpm you make your torque will mathematically increase your horsepower (hp = torque*rpm/5252), but to say that it's impossible for a 2.5L to make 190 lb-ft without making 200+ hp is completely baseless. Torque is dependent on volumetric and thermal efficiency of the engine. Volumetric efficiency can be improved by forced induction (to over 100%), but it's far from the only way. The valve design, fuel injection and induction system can all improve volumetric efficiency. Thermal efficiency can be improved by, for example, increased compression ratio.

      Jayson and fordman, give it up.

      fordman, dont talk about things you dont know shit about. you can optimise an engine for peak torque, flat torque, peak power (torque at high rpm), low end torque, or any combination of the above.

      at some point torque will go down to make more power, a rise in hp does not necessarly equate to a rise in torque.

      basically, without knowing more about where an engine produces its torque, you cannot say things like
      "as hp goes up torque goes up by less.
      at 200hp, torque would be around 187 "
      and
      "At 240hp high rev engine, torque would be around 195 "

      for 195 lbft to make 240 hp, you would need at least 6430 rpm. even then you would have to be making 195 lbft @ 6340 rpm for 240 hp. in the real world, engines loose torque as revs climb, its just harder to make torque at high rpm. so for a real world engine to make 240 hp from 195 lbft it would make its peak torque at something like 5500 rpm and peak power at something like 7000.

      the 2.0 s2000 made 240 hp at something like 8500 rpm. it needed the revs because it couldnt make that much torque.

      there are a lot of people oversimplifying torque and horsepower relationship. which is kinda silly because it is actually really simple. you just need to know rpm to be able to say anything about either.
      • 8 Years Ago
      30. Err, isn't the torque:hp ratio dependant on the stroke vs. bore? Case in point: Chrysler 2.2 and 2.5's. I'm not going to go into the nitty gritty but if an engine is undersquare by enough it'll produce more torque than hp due to relatively low displacement and a long stroke.

      this is exactly the case with the QR25 in the sentra. it's an undersquare engine and makes far more torque per hp. In many ways, it's a truck engine, as they use it similarly as the old KA24 from the old altima. in fact, they use it as the base 4 banger for the new frontier.

      DO ANY OF YOU IDIOTS even own a spec v ?!!!
      I can't believe so many people have such uninformed
      opinions. Here is the real tilt on one great car! I know because i've got one!
      You do the math. (stats from nissanperformancemag.com)
      HP TORQUE
      stock 175 185
      intake 5 6
      headers 11 9
      exhaust 3 6
      ________________
      194 206

      I know you might say that you can't add wheel stats(dyno) and crank hp(used by manf.) but gains would be proportional. These were easy mods done in 6 hrs at home.

      torque more than hp?
      Torque can only be more than hp if the engine is big and very low tech. Like ford 4.6 or 5.4 or other detroit engines.
      Also, 190 torque needs about 2.8 liters od displacement. At 2.5 it can make 190 but hp would have to be considerably more.
      Or supercharge it.
      • 8 Years Ago
      Those torque numbers seem way out of line for a 2.5 engine with no forced induction. I don't think Nissan is going direct injection with this either. Just because a manufacturer boosts HP doesn't mean they'll automatically be able to boost torque significantly without increasing displacement.

      For 3 and 4, since your comments were so far off base, torque is a function of displacement, horsepower is a function of RPM.
      • 8 Years Ago
      yeah, the previous generation 2.5 in the SE-R SPec V was rated at
      HP
      175 @ 6000 RPM
      Torque (lb-ft)
      180 @ 4000 RPM

      So this is a nice step up.

      Alos Nissan has a 2.5 v6 that makes 210hp and 195 torque, and theres an update to this motor coming soon as well that will probabaly have higher numbers (skyline engine)

      Numbers do go up over the years, heck my 92 nissan 2.4 is rated at 160 torque and 155 hp...


      But onto the car itself... prime example of whats wrong with the auto industry in general... bloatware updateing of models
      • 8 Years Ago
      What a sorry successor to the original. Timeline recap!

      1991: Sentra SE-R debuts to become the best sport compact in the history of mankind (hyperbole? what's that?) with a sweet engine, good speed (7.3 sec), nice torque, perfect steering, great handling, 2,500 pounds, and low price

      1995: blobby-looking 200SX SE-R shaves the redline, slugs down the steering, installs embarrassing clunky beam axle suspension

      2000: new Sentra, repeat of last Sentra except size and weight go up, build quality goes down; 2002 mid-life update gives us a new lame 6,000 RPM engine

      2007: freakin electric steering murders whatever road feel remained, chassis fattened all the way to MID-SIZE, weight goes up again to about 3,100 pounds (same as a 95 Maxima) to make it even slower than the original

      Remember kids: fear not death, but the disgraced life.

      JUST FYI -

      To all the nay-sayers, the current 2.5 that is being used in the 2007 Altima produces 175hp and 180lb.-ft. torque, so it's not too far off to believe that in the SE-R this engine could produce 185hp and 190lb.-ft. torque. I wouldn't be surprised if they even squeezed 190hp and 200lb.-ft. out of it. Come to think of it, thats as much power as the original 3.0 VQ V-6 in the 95-99 Maxima had.
      • 8 Years Ago
      It's a Sentra...nothing to be excited about.
      • 8 Years Ago
      16- Here's a novel idea. How about actually DRIVING ONE before tou trash it. My kid's best friend has a 2004 V-Spec that I had the fun of driving last week.

      I haven't had that much fun since I test drove and M5 and CLK 55 AMG on the same day, and for a small fraction of the cost. She paid less than $18K for a ROCKET! The new one is probably going to look better, you can tell that.

      ps Crunchy... if you haven't noticed ALL cars have gotten heavier, save Lotus, so cut Nissan a break.
